CHAUSSURE A SYSTEME DE SERRAGE MUNIE D'UN MECANISME POUR FACILITER  SHOE WITH A CLAMPING SYSTEM HAVING A MECHANISM TO FACILITATE
L'OUVERTURE ET LA FERMETURE DE LA CHAUSSURE  OPENING AND CLOSING THE SHOE
La présente invention concerne une chaussure à système de serrage munie d'un mécanisme pour faciliter l'ouverture et la fermeture de la chaussure afin de faciliter le chaussage et le déchaussage. The present invention relates to a shoe with clamping system provided with a mechanism to facilitate the opening and closing of the shoe to facilitate donning and heaving.
Sur la figure 1A, on a représenté de façon simplifiée les éléments essentiels constituant traditionnellement une chaussure à système de serrage 1.  FIG. 1A is a simplified representation of the essential elements that traditionally constitute a shoe with a clamping system 1.
La chaussure comprend une semelle 2 réalisée en matériau caoutchouc, synthétique ou en cuir et une tige 3 réalisée en cuir, textile et/ou synthétique.  The shoe comprises a sole 2 made of rubber, synthetic or leather material and a rod 3 made of leather, textile and / or synthetic.
Comme l'illustre sur la figure 1B, la tige qui est composée d'un nombre de pièces déterminé par la forme esthétique recherchée comprend essentiellement deux parties, une partie avant (I) et une partie arrière (II), assemblées par une couture dite « claquage » 13. La tige 3 une fois mise en forme est assemblée à la semelle, par collage, injection et/ou couture.  As illustrated in FIG. 1B, the rod which is composed of a number of pieces determined by the desired aesthetic shape essentially comprises two parts, a front part (I) and a rear part (II), assembled by a so-called seam. 13. The rod 3 once shaped is assembled to the sole, by gluing, injection and / or stitching.
La partie avant (i) qui enveloppe l'avant du pied comprend un bout 4 et une claque 5 solidaire d'une languette 10. La partie arrière (II) qui maintient le talon et la cheville comprend deux quartiers 7, deux garants 6 disposés de chaque côté du cou-de-pied, et une talonnette 8. De manière connue, les garants 6 sont solidaires des quartiers 7 et se rejoignent sur le dessus du pied. Les deux garants sont reliés par des moyens de serrage de type lacets 9 pour fermer la chaussure. Une rangée d'œillets 12 dans lesquels passent les lacets est réalisée sur les bords libres de chaque garant. The front part (i) which surrounds the front of the foot comprises a tip 4 and a slug 5 integral with a tongue 10. The rear part (II) which holds the heel and the ankle comprises two quarters 7, two guards 6 arranged on each side of the instep, and a heel 8. In known manner, the guarantors 6 are integral with the quarters 7 and meet on the top of the foot. The two guarantors are connected by fastening means of laces type 9 to close the shoe. A row of eyelets 12 in which the laces pass is made on the free edges of each guarantor.
La languette 10 est interposée entre les garants 6 et le cou du pied de l'utilisateur. Cette languette est dans le prolongement de la claque 5 et forme avec les garants une ouverture 11 pour l'insertion et la sortie du pied.  The tongue 10 is interposed between the guarantors 6 and the user's neck of the foot. This tongue is in the extension of the slap 5 and forms with the guarantents an opening 11 for the insertion and exit of the foot.
Lorsque la chaussure est fermée, la traction exercée sur les lacets 9 permet de serrer et plaquer la partie arrière composée de garants 6 et de quartiers 7 ainsi que la languette 10 sur le pied de l'utilisateur.  When the shoe is closed, the traction exerted on the laces 9 makes it possible to tighten and flatten the rear part composed of guards 6 and quarters 7 and the tongue 10 on the user's foot.
Une chaussure munie d'un tel système de serrage permet d'ajuster le serrage des lacets en fonction du cou-de-pied de l'utilisateur. En outre, dans le cas des chaussures montantes, ce type de système de serrage permet également d'ajuster au plus près des malléoles. Ainsi ce type de fermeture et de serrage offre un très bon maintien du pied dans la chaussure. A shoe provided with such a clamping system makes it possible to adjust the tightening of the laces according to the instep of the user. In addition, in the case of high shoes, this type of clamping system also allows to adjust closer to the malleoli. Thus this type of closure and tightening provides a very good foot support in the shoe.
Un tel mécanisme de fermeture et de serrage présente néanmoins les Inconvénients suivants : Afin de faciliter l'insertion et la sortie du pied lors de la phase de chaussage et de déchaussage, il est nécessaire de défaire les nœuds, de desserrer plus ou moins les lacets, ou même de les ôter partiellement en fonction du cou-de-pied de l'utilisateur et de la hauteur de la chaussure. En effet, l'ouverture de la chaussure 11 est limitée par la présence des moyens de serrage 9 qui emprisonnent la languette 10 ainsi que les deux garants 6. Pour pouvoir élargir l'ouverture 11 en écartant les deux garants pour relever la languette 10, il est donc nécessaire de desserre plus ou moins les lacets. Ces opérations peuvent être perçues comme fastidieuses par l'utilisateur, en particulier sur les chaussures montantes type basket ou bottillon.  Such a closing and tightening mechanism nevertheless has the following drawbacks: In order to facilitate the insertion and the exit of the foot during the booting and heaving phase, it is necessary to undo the knots, loosen more or less the laces , or even partially remove them depending on the instep of the user and the height of the shoe. Indeed, the opening of the shoe 11 is limited by the presence of the clamping means 9 which trap the tongue 10 and the two guarantors 6. To widen the opening 11 by removing the two guarantors to raise the tongue 10, it is therefore necessary to loosen more or less the laces. These operations can be perceived as tedious by the user, in particular on the high shoes basketball or boot.
Dans le cas des chaussures pour enfants, le système de serrage ne permet pas une grande autonomie de l'enfant s'il n'a pas encore appris à faire les lacets. Il sera sans cesse obligé de demander à un adulte de lui enlever ou de lui remettre ses chaussures. Les chaussures à lacets sont même parfois interdites dans les écoles du fait de la nécessité d'assister les enfants lors du chaussage et déchaussage. In the case of children's shoes, the tightening system does not allow a large autonomy of the child if he has not yet learned to make the laces. He will always have to ask an adult to remove him or give him his shoes. Lace-up shoes are sometimes even banned in schools because of the need to assist children during the boot and heaving.
Des solutions alternatives existent et consistent à utiliser des systèmes sans lacets tels que les brides vêleras* ou des systèmes mixtes avec lacets et une ou deux fermetures à glissière latérales sur les quartiers. Le système à bride velcro* permet aux enfants d'être complètement autonomes avec leurs chaussures. Toutefois il n'offre pas, en revanche un maintien aussi bon que les lacets. Ils sont parfois même déconseillés pour certaines activités sportives qui sollicitent fortement les pieds, en particulier un maintien ferme au niveau des malléoles.  Alternative solutions exist and consist of using lace-free systems such as calf straps * or mixed systems with laces and one or two side zippers on the quarters. The velcro strap system * allows children to be completely independent with their shoes. However it does not offer, however a maintenance as good as the laces. They are sometimes even discouraged for certain sports activities which strongly solicit the feet, in particular a firm maintenance at the level of the malleoluses.
Le système à fermeture à glissière latérale redonne aux enfants une autonomie relative selon la longueur de la glissière qui conditionne l'ouverture et l'entrée du pied. La fermeture à glissière est parfois difficile à manipuler pour les enfants et nécessite également l'assistance d'un adulte. En outre, la fermeture est très fragile, elle peut se bloquer ou casser très facilement. Cest une pièce très difficile et très coûteuse à remplacer. The side zipper system gives children a relative autonomy depending on the length of the slide that conditions the opening and entry of the foot. The zipper is sometimes difficult to handle for children and also requires the assistance of an adult. In addition, the closure is very fragile, it can hang or break very easily. It is a very difficult and very expensive piece to replace.
Le document US-2008/0235987 décrit une chaussure qui, par rapport à la chaussure visible sur la figure 1A,comprend des garants reliés de manière détachable aux quartiers arrières.Document US-2008/0235987 discloses a shoe which, in relation to the boot visible in FIG. 1A, comprises guards connected in a detachable manner to the rear quarters.
Cette solution ne facilite pas l'introduction du pied dans la chaussure. Le document US-2008/0201986 décrit une chaussure qui, par rapport à la chaussure visible sur la figure 1A, comprend deux garants reliés entre eux de manière à former une pièce en U, la base de la pièce en U étant reliée sur la partie supérieure de la partie avant de chaussure et les branches de la pièce en U étant reliées grâce à des bandes auto-agrippantes aux quartiers arrières. This solution does not facilitate the introduction of the foot into the shoe. Document US-2008/0201986 discloses a boot which, in relation to the boot visible in FIG. 1A, comprises two guards connected together so as to form a U-shaped piece, the base of the U-piece being connected to the part upper part of the front part of the shoe and the branches of the U-shaped part being connected by means of self-gripping strips to the rear quarters.
Même si cette solution permet de pouvoir introduire le pied sans avoir besoin de défaire les lacets, elle ne facilite pas l'introduction du pied dans la chaussure.  Although this solution allows to introduce the foot without the need to undo the laces, it does not facilitate the introduction of the foot into the shoe.
Aussi, la présente invention vise à remédier aux inconvénients de l'art antérieur, en proposant une chaussure à système de serrage munie d'un mécanisme qui permet une large ouverture de la chaussure pour faciliter le chaussage et le déchaussage sans défaire les moyens de serrage quelle que soit la hauteur de la tige ou le cou-de-pied de l'utilisateur, tout en offrant un très bon maintien du pied et permettant ainsi même aux enfants en bas âge de mettre seuls des chaussures à lacet basses ou montantes.  Also, the present invention aims to overcome the drawbacks of the prior art, by providing a shoe clamping system provided with a mechanism that allows a wide opening of the shoe to facilitate donning and heaving without undoing the clamping means regardless of the height of the user's upper leg or instep, while providing a very good foot support and allowing even young children to wear low or high lace-up shoes alone.
A cet effet, l'invention a pour objet une chaussure à système de serrage comprenant une semelle et une tige, la tige comprenant une partie avant et une partie arrière, l'invention étant caractérisée en ce que la partie arrière comprend deux quartiers délimitant dans une zone de serrage une découpe et en ce que la tige comprend une partie centrale composée de deux garants qui sont reliés chacun d'une part à la partie avant par une première couture qui s'étend à partir de la semelle, et d'autre part, à la partie arrière par une deuxième couture qui s'étend à partir de la semelle, les parties avant, centrale et arrière étant fixées à la semelle, les deux garants étant munis d'une part de moyens de serrage pour maintenir fermés les deux garants, et d'autre part de moyens de fixation pour venir se fixer de manière détachable sur les deux quartiers de la partie arrière en recouvrant la découpe.  To this end, the subject of the invention is a shoe with a clamping system comprising a sole and a rod, the rod comprising a front part and a rear part, the invention being characterized in that the rear part comprises two quarters delimiting in a clamping zone a cutout and in that the rod comprises a central part composed of two guarantors which are each connected on the one hand to the front part by a first seam which extends from the sole, and on the other hand on the other hand, at the rear part by a second seam which extends from the sole, the front, central and rear parts being fixed to the sole, the two guards being provided on the one hand with clamping means to keep the two guarantors, and secondly fixing means for detachably attaching to the two quarters of the rear portion covering the cut.
Avantageusement, la partie avant comprend un bout, une claque et une languette, la couture entre la partie centrale et la partie avant ou la partie arrière formant une zone de liaison qui s'étend sur une hauteur sensiblement égale à trois quart de la hauteur de la claque.  Advantageously, the front part comprises a tip, a slap and a tongue, the seam between the central portion and the front portion or the rear portion forming a connecting zone which extends over a height substantially equal to three quarters of the height of the slap.
Selon une forme préférée de l'invention, la chaussure comporte les caractéristiques suivantes : According to a preferred form of the invention, the boot has the following characteristics:
- la découpe a une longueur (I) sensiblement supérieure à la mi- longueur (L/2) de la tige. - les moyens de fixation comprennent une paire de bandes de matériau d'accrochage et de crochet ; - les garants présentent au moins une partie libre apte à être rabattue vers l'avant de la chaussure en laissant découverte entièrement la découpe ; - The cut has a length (I) substantially greater than the mid-length (L / 2) of the rod. the fastening means comprise a pair of strips of hooking material and hook; - The guarantors have at least one free portion adapted to be folded towards the front of the shoe by leaving fully uncovered the cut;
- une languette est interposée entre les garants et les quartiers ;  - a tongue is interposed between the guarantors and neighborhoods;

Selon un aspect essentiel de l'invention, la tige 23 de la chaussure comprend une partie avant (A), une partie centrale (B) et une partie arrière (C). Les trois parties sont assemblées entre elles par des coutures dites de claquage et sont toutes les trois fixées sur la semelle 22 après la mise en forme par tous moyens appropriés. Ainsi, les coutures de claquage s'étendent à partir des bords des parties avant (A), centrale (B) et arrière (C) reliés à la semelle 22. According to an essential aspect of the invention, the upper 23 of the shoe comprises a front part (A), a central part (B) and a rear part (C). The three parts are assembled together by so-called breakdown seams and are all three fixed on the sole 22 after shaping by any appropriate means. Thus, the breakdown seams extend from the edges of the front (A), central (B) and rear (C) parts connected to the soleplate 22.
La partie centrale (B) comporte une zone de serrage (S). The central portion (B) has a clamping zone (S).
La partie avant (A) comprend un bout 24, une claque 25 et une languette 30. Elle enveloppe l'avant du pied jusque dans la région du cou-de-pied.  The front portion (A) includes an end 24, a slap 25 and a tongue 30. It wraps the forefoot into the region of the instep.
La partie arrière (C) comprend deux quartiers 27, 27' et une talonnette 28. La partie arrière maintient le talon et la cheville. Les deux quartiers 27, 27' et la talonnette 28 sont reliés ensemble par une coutwe. LeiS deux quartiers comportent  The rear portion (C) comprises two quarters 27, 27 'and a heel 28. The rear portion maintains the heel and the ankle. The two quarters 27, 27 'and the heel 28 are connected together by a coutwe. The two districts comprise
délimitent une découpe 38 dans la partie arrière (C). Selon une forme de réalisation de l'invention, la partie centrale (B) comprend deux garants 26, 26' qui comportent des moyens de serrage 29 dont la zone de serrage (S) s'étend depuis une extrémité libre des garants jusque dans une zone de liaison entre les garants et la partie avant (A) d'une part et d'autre part entre les garants et la partie arrière (C). delimit a cutout 38 in the rear portion (C). According to one embodiment of the invention, the central portion (B) comprises two guards 26, 26 'which comprise clamping means 29 whose clamping zone (S) extends from a free end of the guarantors into a liaison zone between the guarantors and the front part (A) on the one hand and secondly between the guarantors and the rear part (C).
Selon un concept essentiel de l'invention, les deux garants 26, 26' sont distincts de la partie arrière. A une extrémité orientée vers la semelle, le garant est relié par une couture le long d'un bord 43, 44, d'une part à la partie avant et d'autre part à la partie arrière. La zone de liaison s'étend sur une hauteur sensiblement égale à trois quart de la hauteur de la claque 25. De cette façon, les deux garants restent libres en mouvement par rapport à la partie arrière. En particulier, les deux garants sont rabattables vers l'avant de la chaussure en laissant la découpe 38 entièrement découverte. According to an essential concept of the invention, the two guarantors 26, 26 'are distinct from the rear part. At one end oriented towards the sole, the guarantor is connected by a seam along an edge 43, 44, firstly to the front part and secondly to the rear part. The connecting zone extends over a height substantially equal to three quarters of the height of the slice 25. In this way, the two guarantors remain free in movement with respect to the rear part. In particular, the two guarantors are foldable towards the front of the shoe leaving the cutout 38 fully uncovered.
Les garants sont munis de moyens de fixation pour venir se fixer de manière détachable sur les deux quartiers 27, 27'de la partie arrière (C) en recouvrant la découpe 38.  The guarantors are provided with fixing means for detachably fixing on the two quarters 27, 27 'of the rear part (C) by covering the cutout 38.
Selon l'exemple illustré, les moyens de serrage sont de type lacets 29. Chaque garant comporte une rangée d'ceillets 42 permettant le passage des lacets. According to the illustrated example, the tightening means are laces type 29. Each guarantor comprises a row of eyelets 42 allowing the passage of laces.
Selon un mode de réalisation, de chaque côté de la chaussure, la distance séparant la découpe 38 et la rangée d'ceillets 42 est sensiblement constante.  According to one embodiment, on each side of the shoe, the distance between the cutout 38 and the row of eyelets 42 is substantially constant.
Les deux garants sont munis de moyens de fixation sur une zone de la face interne pour venir se fixer sur la partie arrière 27, 27' en recouvrant entièrement la découpe 38.  Both guarantors are provided with fixing means on an area of the inner face to be fixed on the rear portion 27, 27 'completely covering the cutout 38.
Selon une forme préférée, une bande de matériau d'accrochage (auto-aggrippante) de type « Velcro » velours 35 est cousue sur une bordure latérale de chaque garant 26, 26', sur la face orientée vers les quartiers, et une bande de matériau de crochets 34, 34' de type « Velcro » crochet est cousue sur une bordure de la découpe de chaque quartier 27, 27', les deux bandes coopérant ensemble pour la fixation des garants 26, 26' sur les quartiers 27, 27'. In a preferred form, a Velcro-type fastening material (Velcro) strip 35 is sewn on a side edge of each guarantor 26, 26 ', on the quarter-facing side, and a strip of material hooks 34, 34 'type "Velcro" hook is sewn on a border of the cutout of each quarter 27, 27', the two bands cooperating together for fixing guarantors 26, 26 'on the quarters 27, 27' .
Pour couvrir la découpe 38 et fermer la chaussure, les deux garants 26, 26' comportent donc d'une part un système de serrage qui permet de fermer la chaussure via les deux garants et d'autre part, un système de fixation qui permet de fixer les deux garants sur les quartiers en recouvrant la découpe. Les deux systèmes sont complémentaires et indépendants l'un de l'autre. Il est donc possible d'adapter l'utilisation de l'un des deux systèmes en fonction du besoin de l'utilisateur. To cover the cut 38 and close the shoe, the two guards 26, 26 'therefore comprise on the one hand a clamping system that closes the shoe via the two guarantors and on the other hand, a fastening system that allows to fix the two guarantors on the neighborhoods by covering the cut. The two systems are complementary and independent of each other. It is therefore possible to adapt the use of one of the two systems according to the needs of the user.
Selon une forme préférée, la découpe 38 s'étend dans une zone sensiblement égale à la zone de serrage (S). La longueur f de la découpe est de préférence sensiblement supérieure à la mi- longueur L/2 de la tige, L étant ia longueur totale de la tige. La largeur de la découpe est sensiblement supérieure à la largeur de la zone de serrage. According to a preferred form, the cutout 38 extends in a zone substantially equal to the clamping zone (S). The length f of the cut is preferably substantially greater than half length L / 2 of the rod, L being the total length of the rod. The width of the cut is substantially greater than the width of the clamping zone.
Selon une forme préférée de l'invention, les moyens de serrage s'étendent sur toute la longueur des garants.  According to a preferred form of the invention, the clamping means extend over the entire length of the guarantors.
Ainsi, grâce à la configuration spécifique de la tige de ia présente invention en rendant les deux garants distincts des quartiers, les garants, même dans un état assemblés par les moyens de serrage, présentent une partie libre, apte à être rabattue vers l'avant de ia chaussure en laissant découverte entièrement la découpe 38. La longueur de cette partie libre rabattable est sensiblement égale à la longueur de la découpe t Thus, thanks to the specific configuration of the rod of the present invention by making the two guarantors distinct neighborhoods, guarantors, even in a state assembled by the clamping means, have a free portion, adapted to be folded forward The length of this free folding part is substantially equal to the length of the cut-out.
Selon une forme préférée de l'invention, la chaussure comprend une languette 30 qui est Interposée entre les garants 26, 26' et le pied quand la chaussure est fermée. La languette 30 a une largeur sensiblement supérieure à la largeur de la découpe 38 et inférieure à la largeur des deux garants. According to a preferred form of the invention, the shoe comprises a tongue 30 which is interposed between the guards 26, 26 'and the foot when the shoe is closed. The tongue 30 has a width substantially greater than the width of the blank 38 and less than the width of the two guarantors.
La languette 30 a donc pour fonction de protéger la partie supérieure du pied contre les frottements des moyens de serrage.  The tongue 30 therefore has the function of protecting the upper part of the foot against the friction of the clamping means.
Selon une forme avantageuse, la languette 30 est munie d'un passant 31, sur une face orientée vers les garants. Ce passant permet d'insérer le moyen de serrage et de maintenir la languette centrée entre les garants. En outre, grâce à la présence de ce passant le mouvement des garants lors de l'ouverture ou de la fermeture sur les quartiers entraîne automatiquement la languette 30.  According to an advantageous form, the tongue 30 is provided with a passer 31 on one side facing the guarantors. This passer allows to insert the clamping means and maintain the tab centered between the guarantors. In addition, thanks to the presence of this passerby the movement of the guarantors when opening or closing on the neighborhood automatically drives the tongue 30.
De préférence, la languette 30 est dans le prolongement de la claque 25 et forme avec elle une pièce unique.  Preferably, the tongue 30 is in the extension of the slab 25 and forms with it a single piece.
En rendant les garants qui supportent les moyens de serrage distincts de la partie arrière, le mouvement des garants ainsi que celui de la languette ne sont plus limités par les moyens de serrage, ils comportent une large partie libre rabattable vers l'avant de la chaussure, en laissant entièrement découverte la découpe de la partie arrière.  By making the guards that support the clamping means separate from the rear part, the movement of the guards and that of the tongue are no longer limited by the clamping means, they comprise a large free part foldable towards the front of the shoe , leaving fully uncovered the cutout of the back.
Lors de ia première utilisation de la chaussure, les lacets 29 sont défaits et les garants 26, 26' ne sont pas fixés sur la partie arrière (C), l'utilisateur peut donc insérer facilement son pied dans la chaussure grâce à la large ouverture formée par ia découpe 38. Les deux garants 26, 26' sont ensuite fixés sur la partie arrière (C) en recouvrant la découpe 38. La languette 30 est ensuite interposée sur  At the first use of the shoe, the laces 29 are undone and the guarantors 26, 26 'are not fixed on the rear part (C), the user can easily insert his foot in the shoe thanks to the wide opening formed by the cut 38. The two guards 26, 26 'are then fixed on the rear part (C) by covering the cutout 38. The tongue 30 is then interposed on
partie arrière (C). L'utilisateur utilise le système de serrage pour ajuster le maintien de son pied dans la chaussure en insérant au préalable les lacets 29 dans le passant 31 de la languette 30 et fermer la chaussure. rear part (C). The user uses the clamping system to adjust the hold of his foot in the shoe by inserting beforehand the laces 29 in the loop 31 of the tongue 30 and close the shoe.
L'utilisateur peut désormais utiliser uniquement les moyens de fixation constitués par les bandes de Velcro 35, 35' des deux garants en laissant les lacets en position de serrage pour le chaussage et le déchaussage.  The user can now use only the fastening means constituted by the Velcro strips 35, 35 'of the two guards leaving the laces in the clamping position for donning and heaving.
Bien entendu, lorsque l'utilisateur doit utiliser les chaussures dans des conditions qui nécessitent un très bon maintien du pied dans la chaussure, il peut serrer plus ou moins les lacets 29 pour réajuster le maintien du pied dans la chaussure.  Of course, when the user must use the shoes in conditions that require a very good support of the foot in the shoe, it can tighten more or less the laces 29 to readjust the maintenance of the foot in the shoe.
La chaussure à système de serrage de la présente invention est particulièrement adaptée pour des personnes qui présentent un cou-de-pied fort grâce à la large ouverture conférée par la découpe.  The shoe clamping system of the present invention is particularly suitable for people who have a strong instep through the wide opening imparted by the cut.
La chaussure à système de serrage de la présente invention est également très adaptée pour les enfants qui sont en phase d'apprentissage. L'enfant peut par exemple utiliser uniquement le système de fixation à l'école en laissant les lacets en position de serrage et apprendre à faire les lacets uniquement à la maison.  The snap shoe of the present invention is also very suitable for children who are learning. For example, the child may only use the fastening system at the school, leaving the laces in the tightening position and learning to lace-up only at home.
On peut également, sans sortir du cadre de l'invention, prévoir d'autres types de moyens de serrage classiques tels que des moyens de serrage sous forme de brides ou de boucles.  It is also possible, without departing from the scope of the invention, to provide other types of conventional clamping means such as clamping means in the form of flanges or loops.
